Has anybody heard anything about the availability of these parts? As far as I can tell they never shipped as non-Us, so I'm wondering if there's a plan to ship them as Us. 32A4U is the biggest I'm aware of as currently available.

Crap! In my zeal I didn't notice (until just now) that 64TQFP package. Well, I guess I can hope that's the part that's wrong, and not the part #. If I get lucky, I'll share the news with the forum ... after I buy up the rest of the stock. ;-)

FWIW, I brought this issue to Digikey's attention, and this was their reply (remarkably on a Saturday):

I have researched your inquiry with our Technical Department. Our website references the wrong description. You will be receiving the part ordered, -ATXMEGA128A4U-AU-ND (44TQFP). Our website will be revised to reference the correct description for this part.

Thank you for bringing this concern to our attention.

Now, I won't receive the parts until next week, so I won't be able to confirm until then, but if you feel like gambling, get your orders in now.

I'd love to have a few 128s for my AV and USB boards (I've already had a couple of customers mention them), but unfortunately, I can't order from the U.S. digikey. The U.K. digikey turns up nothing in searches (no matter how specific) :(

I use them in a small, general purpose board of my own design which I use in many of my projects, which tend to be kinetic sculpture like this: http://www.youtube.com/watch?v=o... (though that one's using a Mega2561). The current project involves an animatronic eye that tracks the viewer. I've never actually used even 32K of flash, but I always like having headroom, hence my quest for 128K parts. For my purposes, the ~$1 difference in price is immaterial.
